NHTSA Complaint #11481088 — 2014 KIA SOUL

My catalytic converter failed and lead to no compression in cylinder 1 of the engine. I scanned the car on 3 different OBD scanners and I had P0420 and P0300 and P0301 codes. Also, the car has the symptoms of bad catalytic converter, which are 1) rattling sound from the exhaust 2)really hot air coming out of the exhaust 3)heat coming out from the center console inside the car, which is right above the catalytic converter 4) engine running rough and doesn't have power I checked on NHTSA website that the car has a recall on the catalytic converter as it says and I saw the flow chart of the procedure which says that if the car has P0420, check for P030X. If it has both codes, check engine compression and if it failed, replace catalytic converter and short block. So, I scheduled an appointment at Beyer KIA Falls Church, Virginia on Wednesday 8/24/2022 at 11AM. They took the car to check the recall, I mentioned that I have the symptoms of a bad catalytic converter and asked to do the recall and not to do anything else without getting back to me. I received a call after 2 hours from them saying that they updated the ECU logic and they don't see a P0420 code and they only see codes P0300 and P0301, they also said that they did a compression test for the engine and Cylinder 1 does not have compression in it. I told them that this means the catalytic converter went bad and it ruined cylinder 1 because it's in bank1 of the engine which is related to the catalytic converter. They said that there is nothing they can do and the car needs an engine. I have the flow chart of the procedures, what i'm trying to understand is how did they do a compression test without P0420 code? I think they found out the engine went bad because of the catalytic converter and they cleared the ECU to prevent replacing both the catalytic converter and the engine. I have proof of the P0420 code on my scanner which will be uploaded with the flow chart of the recall. Please I need help with this ASAP.
